Claims.

The device forming the subject matter. of this application is adapted to be used to build concrete walls, moldboards being raised step by step to erect a concrete wall one course at a time. The invention aims to provide novel means for mounting the moldboards on the posts for adjustment, and for holding them-securely in place. Another object of the invention is to provide novel means for holding the moldboards against outward convexing or inward concaving.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and. other objects. in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the :precise embodiment of the invention herein disclosed, may be made within the scope of what, is claimed, without-departing from the spirit of, the invention.

In the accompanying drawings:

In carrying out the invention, external corner posts I and internal corner posts 2 (Fig. 1) are erected, the posts being angle members. Intermediate posts 3 are set up between the corner posts I and the corner posts 2, and are T members. The bodies of the intermediate posts 3 project outwardly, that is, away from the finished wall W, a feature the utility of which will be made manifest hereinafter. At the upper ends of the posts 3-, the transverse heads of the posts are. cut away, as shown at 4 in Fig. 5, to receive horizontal ties 5, attached to the bodies of the posts by securing elements 6. To provide for walls W of different thicknesses, the ties 5 have spaced openings I for the reception of the securing elements 6.

Outermoldboards 8 extendtbetween the external corner'posts I and the adjacent intermediate posts 3, and between adjacent intermediate posts 3. Inner moldboards 9 are located similarly with respectv to the internal corner posts 2 and the corresponding intermediate posts 3. The moldboards-8 and 9 that are adjacent to the corner posts I. and 2 are recessed as indicatedat, III in Fig. 1', to receive. the flanges of the corner posts, and the. ends of the moldboards that are adjacent. to the intermediate posts 3 are recessed to receive the heads of the intermediate posts. This recessing of the moldboards 8 and 9 at their ends will be understood best if notice is taken of the recess lb of Fig. 9, although that View is a modification, the change being in respects other than the; cooperation between the moldboards and the posts.

The. reasons for having the bodies of the intermediate postsv 3 project outwardly, to wit, away'from the finished wall W, now may be set forth. Sincethe moldboards 8 and 9 are recessed, for instance as shown at IUb in Fig. 9, the surfaces of: the heads of theT-shaped intermediate posts 3, and the corresponding surfaces of the moldboards, which have contact with the wall W, are flush, and no gashes or cracks are formed inthe wall by the bodies of the posts 3. Moreover, because the bodies of the posts 3 do not extend into the wall W, the reenforcements I I in the wall may be placed close to thesurfaces of the wall, where they belong if they are to have maximum eificiency.

In order to sustain the moldboards 8 and 9 against flexing toward each other, cross braces I2 are placed on top of them, as in Fig. 6, the braces presenting vertical shoulders I4 to the facing surfaces of the moldboards. The moldboards 8 and 9 are prevented from flexing away from each other by means of clamps I5 which straddle the moldboards, as in Fig. 6. 'Each clamp I5 comprises a stem It, provided at one end with a fixed, rectangularly disposed jawI'I cooperating with the moldboard 8. A movable jaw I8, disposed parallel to the jaw I1, is mounted to slide on the clamp stem I6, and is urged inwardly against the moldboard 9 by a cam lever l9, pivoted on the end of the stem l6.

Figure 4 shows that the wall W is formed of horizontal courses of concrete. After one course has set sufiiciently, between the moldboards 8 and 9, the moldboards are raised, and a superior course is formed.

In order to provide for the vertical adjustment of the moldboards 8 and 9, and to hold them in vertically adjusted positions, recourse is had to the structure shown in Fig. '7. The structure referred to will be described relatively to the intermediate post 3, its application to the corner posts and 2 being obvious without specific description.

The ends of the moldboards- 8 and 9 are received in substantially U-shaped hangers 20, each comprising a vertical main member 2|. Each main member 2| has a rectangularly disposed top flange 22, provided with an upstanding lip 23. The main member 2| has a rectangularly disposed bottom flange 24, provided with a depending lip 25. The lips 23 overlap the facing surfaces of the heads of the T-shaped posts 3, the flanges 22 and 24 being notched to receive a head of the intermediate post 3, and the flanges of the corner posts I and 2, as shown in Figs. 2 and 3, at 26. When the moldboards have been raised to form a new course in the wall, the flanges 25 overlap the course already fashioned, as can be seen in Fig. 5.

The means for holding the hangers 20 and the moldboards 8 and 9 in vertically adjusted positions, includes an upstanding lug or projection on the top flange 22 of the hanger 20, as shown at 21. A retainer 28 is driven to a seat on the top flange 22 of the hanger 20, between the lug 21 and the lip 23. The retainer 28 may be a piece of metal, triangular in cross section, the acute edge of the retainer acquiring a good hold on the head of the post 3.

In Fig. 8, parts hereinbefore described have been designated by numerals already used, with the sufiix a. The hanger 20a. includes a hookshaped foot 29, shaped to receive the moldboard 7 9a, the foot having an ofiset, upwardly extended shank 30 which fits against the head of the post 3a. The shank 30 of the hanger 20a is provided with an angle bracket 3| which extends around the edge of the head of the post 3a, a set screw 15 32 being threaded into the bracket 3|, for engagement with the head of the post 3a.

In Figs. 9 and 10, parts hereinbefore described have been designated by numerals already used,

with the suffix b. In this form, the bracket 3|bis U-shaped and detachable from the shank 30b of the hanger 20b, the bracketreceiving both the edge of the head of the post 31) and the shank 30 of the hanger.

In Fig. 11, parts hereinbefore described have been designated by numerals already used, with the suffix c. The tie 5c is supplied with a depending wing 33, attached by a securing element 34 to the head of the post 30. The tie 50 has an elongated slot 35. An angle bracket 36 is attached by a securing element 31 to the opposite post, the horizontal flange of the angle bracket forming a rest for the tie 5c, the angle bracket having a threaded stud 38, extended through the slot 35 and carrying a washer and a clamping nut 39. The device of Fig. 11 gives a quicker and finer adjustment as to the space between the moldboards than does the structure shown in Fig. 5.

The moldboard 9 is provided with hollow internal projections 40, and the projections, as the moldboard is raised, form vertical spaces 4| in the wall W. The air spaces 4| may be of any desired length. The use of them saves concrete and affords air spaces where desired. Furring strips 42 may be embedded in the concrete ribs between the air spaces 4|, and insulation 44 and a finishing of plaster or the like, marked by the numeral 45, may be attached to the furring strips.

The general operation of the device may be dismissed with the statement that, by raising the moldboards 8 and 9 on the posts 2 and 3, a concrete wall can be built up course upon course, with a minimum amount of moldboard material and with a minimum amount of supporting structure. The manner in which the hangers of Figs. 7, 8 and 9 operate will be understood readily from the drawings, without description, in view of what has been stated hereinbeiore.

Having thus described the invention, what is claimed is:

1. In a wall mold, a post, a moldboard, a U-shaped hanger receiving one end of the moldboard, and comprising upper and lower flanges between which the moldboard is included, the upper flange having a slot in its edge, receiving one edge portion of the post, there being a lug on the upper flange, and a retainer insertible between the lug and the edge portion of the post.
